A kind of print guide belt fast-drying device
Technical field
The present invention relates to a kind of drying unit, particularly a kind of print guide belt fast-drying device.
Background technology
Machine of magnetic rod printing machine is at home and abroad widely used in dyeing.More manually lift an edition stamp and have that production efficiency is high, stamp color and luster is rich and gaudy, scrape evenly, print penetration is good, easy to operate, etc. advantage.Especially when printing broad fabric, elastic fabric and chemical & blended fabric, efficiency is higher, print guide belt needs skin drying in operation process, drying unit was mounted in conduction band bottom in the past, the fin passing into steam is utilized to carry out heating, drying, because temperature is not too high, cause print guide belt skin drying not thorough, after causing printed fabrics to spread conduction band, water suction is moist, affects fabric printing quality.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of print guide belt fast-drying device of reasonable in design, easy to use, good drying effect.
Technical problem to be solved by this invention is realized by following technical scheme, the present invention is a kind of print guide belt fast-drying device, be characterized in: comprise the far-infrared heater being located at print guide belt one end, described far-infrared heater is covered with fan housing, fan housing is provided with the opening towards print guide belt, the fan housing rear wall just right with fan housing opening is provided with the air inlet being inclined upwardly and arranging, reflector is provided with between fan housing rear wall and far-infrared heater, air intake gap is set between reflector and fan housing upper wall, return air gap is set between reflector and fan housing lower wall, uptake is set between reflector and the upper edge of fan housing opening, uptake is arranged on directly between print guide belt and far-infrared heater, return air inlet is set between reflector and the lower edge of fan housing opening, return air inlet is arranged on the below between print guide belt and far-infrared heater, the wind entered from air inlet is by air intake gap, uptake passes between print guide belt and far-infrared heater, print guide belt is dried, part hot blast is through return air inlet, pre-thermosetting circulated air is carried out to the wind that air inlet enters in return air gap, the intake of described air inlet is 2000-5000 cube m/h, the power of described far-infrared heater is 2-10kw.
Technical problem to be solved by this invention can also be realized further by following technical scheme, and described air inlet and the angle of horizontal plane are 30-60 °.
Technical problem to be solved by this invention can also be realized further by following technical scheme, and described air inlet is the strip air inlet axially arranged along fan housing.
Technical problem to be solved by this invention can also be realized further by following technical scheme, and described air inlet is made up of several airducts axially evenly arranged along fan housing.
Compared with prior art, the present invention is dried print guide belt surface by far-infrared heater, by reflector, far-infrared light is reflexed to conduction band surface simultaneously, further submission heating effect, the air flowing on print guide belt surface is driven additionally by the wind of coming in from air inlet, even heat distributes, and accelerates the evaporation of print guide belt surface liquid, drying efficiency high better effects if.

Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Referring to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
With reference to accompanying drawing 1, a kind of print guide belt fast-drying device, comprise the far-infrared heater 2 being located at print guide belt 3 one end, far-infrared heater 2 is 10-80cm apart from the distance of print guide belt 3, described far-infrared heater 2 is covered with fan housing 1, fan housing 1 is provided with the opening towards print guide belt 3, fan housing 1 rear wall just right with fan housing 1 opening is provided with the air inlet 6 being inclined upwardly and arranging, the air inlet 6 be obliquely installed is 30-60 ° with the angle of horizontal plane, the structure of air inlet 6 can have multiple, being preferably described air inlet 6 is the strip air inlet axially arranged along fan housing 1, or described air inlet 6 is made up of several airducts axially evenly arranged along fan housing 1.Be provided with reflector 4 between fan housing 1 rear wall and far-infrared heater 2, the light of far-infrared heater 2 can be reflexed to the surface of print guide belt 3 by reflector 4, so further rising print guide belt 3 surface temperature.Air intake gap 7 is set between reflector 4 and fan housing 1 upper wall, return air gap 5 is set between reflector 4 and fan housing 1 lower wall, uptake is set between the upper edge of reflector 4 and fan housing 1 opening, uptake is arranged on directly between print guide belt 3 and far-infrared heater 2, return air inlet is set between the lower edge of reflector 4 and fan housing 1 opening, return air inlet is arranged on the below between print guide belt 3 and far-infrared heater 2, the wind entered from air inlet 6 is by air intake gap 7, uptake passes between print guide belt 3 and far-infrared heater 2, print guide belt 3 is dried, and while raising conduction band surface temperature, accelerate the flowing of print guide belt 3 superficial air, the evaporation of print guide belt 3 surface liquid is accelerated.The wind that part hot blast enters through return air inlet, 5 pairs, return air gap air inlet 6 carries out pre-thermosetting circulated air, can save energy like this.The intake of described air inlet 6 is 2000-5000 cube m/h, and the power of described far-infrared heater 2 is 2-10kw.
